Chapter 9, Problem 9.42E

Interpretation Introduction

Interpretation:

The validation of the fact that the equation 9.34 has units of length is to be shown.

Concept introduction:

According to the postulates of Bohr, it is assumed that an electron is present in certain orbits. The Bohr’s radius is calculated by the formula,

$r=\frac{{\in }_{\text{ο}}{n}^2{h}^2}{\pi m_e{e}^2}$

Where,

• $n$ represents the number of orbits and $n$ is a natural number.

The above equation shows that the value of radius is discrete. Thus, they are quantized.
